E Type Long Manifold and Exhaust Systems

Classicfabs manufacture the ultimate in mirror finished stainless steel six branch manifolds. “To vastly improve the performance and appearance of your E-type.”

Technical Features

Increases mid-range torque and horsepower
Minimum primary length 28″
304 x 1.2mm W.T. stainless steel
All T.I.G. welding done using B.O.C. ‘Stainshield’ and pure Argon purge gasses, to give a higher quality, smooth, clean, defect free weld finish.
Machine flared ports for optimal gas flow
1-piece collector
CNC full mandrel bent tubing
Fits 3.8 dynamo cars
Fits with no modification to standard
Link pipes supplied to suit standard or 2″ big bore silencer
Replaces existing system between head and middle silencer

Performance improvements

The long exhaust manifold is best suited to fast road engines such as those with big valve inlets, Weber carburettors, mid porting and wider cams, producing around 250 – 260 bhp compared with the standard engine’s 210 – 220 bhp.

An increase in power of around 5 to 10% can be achieved in the mid range (2500 – 3500 rpm), which gives the engine a stronger torque curve.

Fitting the manifold

No modifications are required to fit the long manifold but when fitting, access is required to the underside of the car. There is no loss of ground clearance with these systems.

If the manifold is fitted to 3.8L cars with a dynamo, a heatshield is recommended. This can be supplied in the fitting kit as required.

Total Investment

As these complex manifolds each take approximately 32 hrs. to manufacture and polish, the cost of the long manifold system including fitting kit is £920.00

Complete system including manifold and ‘Big Bore’ straight through exhaust, complete with all fixings, heat shield and dip stick bracket. Manifold and rear silencer mirror polished as standard. £1490.00

All other mirror polishing extra.
